 more or less transverse scabrous ridges; anterior internal lobe of 

 carpus subacute with several spinules on its margins besides the 

 small apical one; upper longitudinal margin of merus with a single

Figure 51. — Aegla franca, new species, male holotype: a, Dorsal view; b, lateral view of 

 anterior portion; c, sternum of third and fourth thoracic somites; d, inner ventral margin 

 of ischium of left cheliped; e, lateral view of second abdominal epimeron. a, b, natural 

 size; c-e, twice natural size. 



Anterior dorsal angle of epimeron of second abdominal somite more 

 or less blunt-angled ; usually, but not always, with one or more tiny 

 hyaline or corneous spinules or granules at apex of angle; anterior 

 margin below angle about straight. 



Holotype. — The largest of 10 males from Franca, State of Sao 

 Paulo, Brazil, collected in October 1910, by E. Garhe (No. 622), 

 received some years ago as a gift from the late Dr. Hermann von 

 Ihering. The type, U.S.N.M. No. 80019, measures 24 mm. long 

 (carapace and rostrum). 



'Remarks. — This species and the one following have relatively nar- 

 row fronts as compared with the several preceding species (J.^ sec- 

 tion of diagnostic key). Tliis character and the reduced extra- 

 orbital sinuses are suggestive of the species that follow {A' section 

 of ke}^, yet, in general, the more or less ridge-roofed type of rostrum
